Hello to the group. I am tinkering with the leftover xtal oscillators from the lucent RB cel site references. Figured they were nice and might make a useful GPSDO. I have a hp3801 that works fine. Also I am using the vers 1.3 Brooke Shera bd that I resurrected just for tinkering with a Oncore M12+.
I suppose its always been obvious but I really never noticed. When everythings locked the oscillator will drift a bit left or right governed by the filter time of the controller and the S parameter of the EFC and LSD DAC used. Is that a correct observation? This is quite a small drift. I have the scope at 10 ns and the xtal oscillator drifts right and then left at 30 sec intervals min time constant on the controller. Granted I definitely do not have the resistors quite correct yet for the EFC voltage. Thanks for comments in advance.
